Application 4filed October 29, 1908. Serial No. 460,008-

To all whom it may comrrn:

Beit known that l, Tai/Loa W. HEiN'rZnL- MAN, of Sacramento, in thecounty of Sacramento and State of California, have invented a certainnew and useful Improvement in Locomotive Ash-Pans, of which improvementthe followingr is a specification.

My present invention relates to locomotive ash 'pans of I-the generalclass or'type set forth in Letters Patent of the United States Nos.620,707 and 634,728, granted and issued to me under dates ofA March.7,'1899 and October 10, 1899, respectively,' and its object is to providemeans for preventing the discharge slides which control the loweropeningsof the ash pan from being clogged by accumulations of snow orice in the grooves of their guide frames and for enabling them to bereadily thawed out if any water should freeze between the adjoiningfaces of the discharge slides and guide frames.

' The improvement claimed is hereinafter fully set forth.

In the acconmanying drawings: Figure' 1 is a side view, in elevation, ofa locomotive ash pan, illustrating an application of my invention; Fig.2, a plan or top view el thel guide frames and their connections, withthe ash panbody removed; Fig. 3 a plan or topview, on an enlarged scale,of a guide frame detached; FigA, a vertical longitudinal section throughthe same, on the 'line c a of Fig. 3; and, Fi 5, a transverse section onthe line b b of iig. 3.

My invention is herein shown as applied in connection-'with a locomotiveash pan, the

body of which, as in the Letters Patent aforei said, is in the -form ,ofthree connected sheet metal hopper sections, 1, 1,' l, of properthickness, each of which is open at its top, and is tapered inwardly anddownwardly to a dischargeopening at its lower end, around which issecured a guide frame, 3, in lateral grooves or guidewa s, 4, of which,a discharge slide, 6, whic i governs the discharge ripening, is fittedto traverse longitudinally.

he body of the ash pan may be secured to the top rails of the engineframe, 14,1)1' may be supported in any other suitable and preferredmanner. The discharge slides, are connected by pairs of links, 8, witheach other, and with the piston' rod, 12, of a fluid pressure cylinder,11, by the movements oli the piston and rod of which, they are traversedlongitudinally in the grcoves'of the guido frames, 3, to open and closethe diss from time to time re uire to release ashes therefrom,substantial y as in Letters Patent No. 620,707, aforesaid.

In the practice of my )resent invention, I provide each of the guideframes, 3, with a pair of steam chambers, 5, which extend ongitudinallyon itsr sides, outside of and adiacent to the guideways 4. Dischargeholes, 5", extend, through the inner walls of the steam chambers, intothe guideways, and drain holes, 5b, are formed in the bottoms of thesteam chambers, for the escape of water of condensation therefrom.casting, as well as to enable access to be had to the inside of thesteam chambers if desired, their ends are preferably -closed byremovable plugs, 5.

A steam supplypipe, 7, leads from a connection to the boiler oftheim'omotive, conrcach of the engineer to one of the steam chambers, 5, ofthe guide frame of the rear hopper section of the ash pan body, and iscontinued by branchlsuppl pipes 7 1, to connections with steam chambersof the guido frames of the other hopper sections. 'Ihe opg-visite steamchambers of cach guide frame are connected by transverse pipes, 7 b, sothat steam admitted thrugh'thc supply pipe 7, will be fed to all thesteam chambers of the ash pan.

It will be seen that aliyaccunmlatitm of snow or icc on or between theadj acent'surfaces of the guideways and discl'mrge slides,

' may be quickly and completely removed by heating the parts by steamadmitted to the chambers, 5, and discharged therefrom into theguidcways, and by kee )ing the chambers constantly warm by the admissionof a small t uantity of steam, in freezing weather, the liability tofreezing` of an water on their surfaces or on the surfaces offthedischarge slides will be avoided, and the latter will be always incondition to be moved freely.

The cost of thc improvement is inconsidcrable, and it can be appliedwithout interference with any of the members connected with or adjacentto theash pan.

I claim as my invention and desire to secure by Letters Patent:

l. In a locomotive ash pan, the combination of a body havingla dischargeopening, a hollow guide frame fixed to the bottom of the body, adischarge slide iitted to traverse longitudinally in the guide frame,and means 'lo facilitate i' charge openings of the ho )per sect-ions, as

trolle'd by a cock or valve within convenient lic a steam supply pipeleading froin't e boiler of the locomotive to the steam chambers, and adischarge slide fitted to traverse longitudiiially iii the guideways.

lateral guideways communicating therewith,

a discharge slidey fitted to traverse longituditio( iicing a heatingiiiediiiiii iii th"x hollow the giiidcways and discharge slide.

ila-ll f in the guidewais, and ineens l'oi' iiiln zi locoiiiotii'e ashpan, the coiiibiiiaj tion ol' a body having' a diseliaige opening, l'

a guide iianie fixed to the bottoni ol' the body :ind provided withlateral guideways and vsteam chaii'ibei's adjacent to and'coniniiiiiii-,zilingi' with the guidewavs, a steani supply pipeleading,r i'ioni the boiler of the locomotive to the steaiii chaiiihers,and a dischai-ge slide fitted to traverse longitudinal-ly in thegiiideways.

4. In a locomotive ash pan, the combination oi a body having a lowerdischarge opening, a. guide iranie fixed to the bottoni of the l i lbody. and provided with lateral giiideways,

steam' chambers on the `guide frame having l ln a loioiiiotive ash pan,the combination ol a body comprising a pluralit f of hopper sections,having a lower ischarge opening, guide fraiiies fixed to the bottomsoithe hopper sections and provided with giiideways on their oppositesided, steam chambers formed iii the ofuide frames adjai'eiit to thegiiideways, pipes connecting the opposite steam chambers of each guidel'ranie, a ste-uni supply pipe leading frein the boiler ot' thelocomotive to a steain chamber of one ol' the guide frames, branch steampipes leading from the supply pipe to a steam eliaiiiber .oi each of theother guide i'i'ziiiies, and discharge slides fitted to traversolongitudinally iii the guideways of the several guide frames.
